Answer:
Step-by-step explanation:
Assuming this is a linear equation in the form of 
, we can first solve for the slope using 
, for these points, the slope would be 
. Now we plug in the points to get the equation:
plugging in (7,5), we get 
×
+ 
and solving for b, we get b = 
therefore, the equation of the line passing through (7,5) and (1,2) is .
hope this helps!

A) 60,600;6.06×105
B) 60,600;60.6×104
C) 606,000;6.06×105
D) 606,000;60.6×104
Answer: a or b
Answer:
39
Step-by-step explanation:
Let a and b represent the first and second digits, respectively.
... a = b -6 . . . . . . the first digit is 6 less than the second
... a + b = 12 . . . . .the sum of digits is 12 (an even number)
Using the expression in the first equation, we can substitute for a in the second equation:
... (b -6) +b = 12
... 2b = 18 . . . . . . add 6, simplify
... b = 9 . . . . . . . . .divide by 2
... a = 9 -6 = 3 . . . . from the first equation
The number is 39.
